Standard Model extensions that yield observable neutrino magnetic moments typically also induce large neutrino masses, incompatible with experimental limits.
This tension motivates the search for mechanisms that naturally decouple magnetic moments from mass generation without requiring fine-tuning.
In this talk, I propose a novel mechanism for generating Dirac and Majorana neutrino magnetic...
We explore a left–right symmetric model in which both neutrino masses and dark matter stability have a common origin. The dark matter is identified as a pseudo-Nambu–Goldstone boson (pNGB). Its scattering with nucleons is naturally suppressed. At the same time, neutrinos here are pseudo-Dirac particles with Dirac masses generated at the two-loop level. Small Majorana mass terms arise from...
Neutrino mixing parameters receive quantum corrections and therefore evolve with energy. A mismatch between the mixing parameters at the production and detection scales can produce measurable effects in flavor transitions. We investigate an ultraviolet-complete model of neutrino mass that predicts an observable running of the mixing matrix. We evaluate the IceCube sensitivity to this effect,...
A new neutrino-matter interaction can potentially affect neutrino propagation through matter. In this work, we explore the impact of a flavor-conserving scalar-mediated non-standard neutrino interaction in the supernova neutrino flux. We observe that the presence of scalar interaction involving muon and tau neutrinos (parameterized as $\eta_{\mu\mu}$ and $\eta_{\tau\tau}$, respectively) can...
The NuMI Off-Axis Appearance $\nu_e$ (NOvA) experiment is designed to study neutrinos and their interaction properties with matter. NOvA is a long-baseline neutrino oscillation experiment consisting of a Near Detector at Fermilab and a Far Detector in Ash River, Minnesota. Its primary goals are to determine the neutrino mass hierarchy and constrain the charge-parity (CP) violation phase. In...
